ToaZZ whom t may concern.' `3 Beit known thatwe, JOHN ARTHUR KEE- sEY`and ALFRED SHnDLooK, citizens of the United Staf/QS, residing,respectively, at Brooklyn, county `of Kings, State of New York,- and-Cannon`dale, Fairfield county, `State of Connecticut, have jointlyinvented new and useful ImprovementsinSignaling Apparatus, of whichthefollowing is a specification. .f A

The salient feature oit-this invention is providing a ,conical surfacefor the message indications of a signaling apparatus, whereby saidmessages 'may be more readily observed by the operator, while standingnaturally,` than whensuch markings are oli` cylindrical orflat surfaces.This point of advantage is particularly enhanced in multimessageVsending and receiving apparatus. In such cases the conical messageindicator lwill preferably` be arranged on a common `axis in diiferentvertical planes, each having suitable index also operative on the commonaxis. The conical indicato-rs mayfconstitute jthe top of the-frame orcasing of the apparatus, and in multi-signaling appavratus the conicalshells will preferably increasel in sizerfroni the front to the 'rear of1t is also contemplated'to utilize the .conical shells as the gongs ofsound producing mechanism-s, als,` with otherfdetailsV of construction,will now be .described by reference had to the accompanying dra-wings;in

which:

Figure 1I is a plan view of an apparatus embodying our invention.

Fig. 2 isa front elevation. Fig.` 3 is a. longitudinal vertical section,and

Fig.4 is a transverse section on line 4, 4, Fig. 3.r f 4:5V

The casing in which the-w'orkingparts are inclOsed comprises a -frame 5,substantially rectangular, `havingA sider'flanges 6, from 'whichvertically extend irregular shaped flanges 7, and semicircular front andback plates 8 and 9; Theseplates 8 and 9 are,

to facilitate the molding operations prefer- "ably cast-separatelyandseciired by screws or rivets to the front and back walls of the part5, respectively. The top. of `the easing consists of semi-circularconical plates or pulleys 24 and 25'.

shells `10, 11 and 12, on which the messages or orders are painted orotherwise indicated, here shown as communications between the officersand engineers stations. The conical shells are secured to the flanges 7,by screws 13.` There are gaps or spaces between the adjacent circularedges of these plates, between the front edge of the foremost plate 10and the front of the frame and between the back edge of the rear plate12 and the back of the frame. The operating handles 14, 15v and 16,provided Vwith pointers 17, 18 and 19 respectively,'and the returnmessage indices or arrows 20, 21and 22 extend through said gap.

The apparatus shown comprises three distinct message sending andreceiving devices each adapted, through suitable transmittingconnections to operate and be operated by an apparatus located atseparate stations or at separate engines or machines. The advantage ofthe conical message indicator is that "of vision at a suitable angle forobservation.

Centrally supported in the front and back walls of the frame 5 is abearing rod or shaft 23, on which rotate chain wheels or pulleys 24,located beneath the conical plates or shells 10, 11 and 12, and on thesleeve of each of these pulleys is a pulley or wheel 25,

vadapted to be `actuated from a distant station. A chain 26 is carriedby each of the The operating handles 14, 15, 16 are rig- Y idly attachedto the pulleys 24, under the conical shells 10, 1'1 and 12 respectively,and similarly the indices or arrows 20, 21, 22

are attached to the return signal or message pulleys 25.

Y In some cases the return signal devices may be omitted. Aural signalsare sometimes required when return messages are indioated on the mainstation signaling apparatus. To meet this requirement we have devised asimple double acting striking mechanism, as follows, utilizing theconical shells of the casing as the sound giving parts of the frame.Each bracket carries a plate 28, which is held thereon by headed studlbolts 29, embraced by curved slots 30, each.

having its center at the axis of the stud bolt of the other one.Centrally pressing against the lower edge of the plate 28 is a spring3l, whose bottom end is supported on a lug 32, forming pari; ofthe'fbraclret 27. A projection or tooth 33 laterally extends from theupper part of the face of plate 28, so located as to be in the path ofaction of a series of circularly arranged teeth 34`projecting from theside of a return signal pulley 25, adjacent to the double rocking plate28. A spring supported hammer 35 extends upwardly from the plate 28 andis so located normally as to be a short distance from the conicalmessage indicating shell above the striking mechanism. The hammer springis shown as a spiral spring 36, acting as a stem lbetween the hammerandiplate 28, of right resiliency to permit the hammer to rebound`against the bell, that is the conical. shell, 'when the lower end ofeither of the slots 30 Vsuddenly contacts with its stud 29, by theenergy of the spring 3l, after the plate 28 has'been rocked in eitherdirection by and suddenly released from any and all of the teeth 34 of apulley 25. An aural signal is thus given as each of the arrows 20, 2l or22 is moved to the right or left of the zero, or normal, resting mark ofthe message indications, said teeth 34 being spaced to cause the plate28 to be rocked at least once as an arrow moves from message indicationto another. As the resonances of the different sized conical shells, l0,l1, 12, varies a distinctive sound will be produced as the apparatus ateach of the substations is manipulated. i
